Title: Method for the polycondensation of synthetic linear polyesters
Inventor: CONIX ANDRE JAN
IPC: C08K5/56
Filed: 1966-03-17
Abstract: In the manufacture of high molecular weight polyesters by the melt polycondensation of a glycol ester of a dicarboxylic acid in the presence of a polycondensation catalyst, colour formation is reduced by effecting the polycondensation in the presence of a tetrahydrocarbyl germanium compound.  The germanium compounds are preferably added at the beginning of the polycondensation stage but may also be added at the beginning of the ester-interchange reaction. In the examples, ester-interchange was effected between dimethyl terephthalate and ethylene glycol in the presence of praseodymium oxide, zinc acetate, manganous acetate or titanyl iodate and the resulting glycol esters were polycondensed to polyethylene terephthalate in the presence of the tetrahydrocarbyl germanium compound.

Title: Improvements in or relating to the cutting by electric arc of metals and alloys
Inventor: FANNON ROBERT LEYDEN
IPC: B23K9/013
Filed: 1954-04-26
Abstract: 760,270. Dividing by fusion. BRITISH OXYGEN CO., Ltd. April 26, 1955 [April 26, 1954], No. 12026/54. Class 83 (4). A process for cutting metals and alloys comprises feeding a ferrous wire consumable electrode to a high density electric arc struck between the wire and the metal to be out, feeding nitrogen in admixture with an amount of oxygen not substantially greater than 10 per cent by volume of the total gas mixture to surround the arc, and moving the wire relative to the metal to be cut along the line of cut so as to maintain the arc and cut through the metal. The wire electrode is fed from a reel 10 by feed rolls driven by a variable speed electric motor, through a conduit 13 to the cutting gun 12. Nitrogen from a cylinder 14 and oxygen from a cylinder 15 are mixed in the correct proportion, preferably 2 per cent oxygen, in a mixing device 18 which automatically maintains the correct proportion. The mixed gas passes through a tube 19 to the interior of the conduit 13 and thence to the gun 12. A flow indicator 20 for the shielding gas is provided. The arc current is supplied from a direct current generator or a transformerrectifier unit 21 which also supplies current to the motor driving the reel 10. A trigger 26 on the gun controls the feed motor for the electrode and also the flow of shielding gas to the arc. An inching button 30 for starting the arc is fitted. An example is given for the cutting of stainless steel plate in which the feed, current, flow of shielding gas and cutting speed is given. The invention may be also used for cutting copper. Manual or automatic apparatus may be used for moving the wire electrode along the line of cut.

Title: Process and apparatus for the preparation of thermoplastic film
Inventor: GOULD GORDON EUGENE
IPC: B29C55/28
Filed: 1965-03-22
Abstract: 1,093,217. Films. DOW CHEMICAL CO. March 22, 1965 [April 8, 1964], No. 12080/65. Heading B5B. A roll of thermoplastic resinous film of substantially uniform diameter is made by inflating a flattened tubular film, heating the inflated film to a temperature sufficient to remove wrinkles, collapsing the film, and winding it into a roll while causing the film issuing from any given point of the film supply means to describe a generally helical pattern on the inflated portion of the tube. The helical traverse of the film may be provided by causing the supply means for the flattened film and the collapsing means to rotate, relative to each other, about an axis colinear with the axis of the inflated tube. Alternate right and left hand helical traverse may be provided. In one embodiment (Fig. 1), a deflated tubular film 13 from supply roll 11 is fed between guide-plates 30, 31, inflated by insertion of an air-hose between the film layers and then sealing the puncture, passed through ovens 35, 36, collapsed by converging rolls 47 and wound up at 58. The roll support assembly 20 is carried by platform 19, which is supported on bearings 22, and is rotatable by means of gear-box 25 and motor 26. In operation, the relative rotation between the nip rolls 14, 15 and the nip rolls 53, 54 is maintained at a rate sufficient to cause a lengthwise line drawn upon the flattened film prior to entering nip rolls 14, 15 to cyclically deviate through at least 360 degrees or integral multiples thereof at the collapsing rolls, thereby obtaining complete randomization of any irregularities in the film. Fig. 2 shows the randomizing action when film from a supply roll 60 is passed, after inflation through an annular oven 64 and is collapsed by wind-up rolls 65 which are rotating relative to the supply roll. In further embodiment, the film wind-up station may be made to rotate or oscillate while the film supply means and the oven are fixed relative to each other. The film supply means may be an extrusion die instead of a wound roll, in which case, to avoid incomplete randomization caused by twisting of the melt at the die, the extruded film bubble is first collapsed and then re-inflated. The process is applicable to tubular films of polystyrene, polyvinyl toluene, polyolefins, polymers and copolymers of vinyl chloride, vinyl acetate and vinylidene chloride, and copolymers of vinylidene chloride and acrylonitrile. Examples describe the processing of polypropylene films.
